Equipment Needed

To create these delightful brownies, you’ll want to have a few key pieces of equipment on hand:

• A 13x9x2-inch baking pan
• A large mixing bowl for the batter
• A separate bowl for the peanut butter filling
• A medium bowl for the frosting
• A whisk or electric mixer for the batter and filling
• A rubber spatula or offset spatula for spreading
• An oven, preheated and ready to go
• A wire cooling rack

Instructions

Bringing these Ooey Gooey Peanut Butter and Fudge Brownies to life is a rewarding process. Follow these steps carefully for the most spectacular results:

1. Preheat and Prepare: Begin by preheating your oven to 350 degrees F (175 degrees C). Next, grease the bottom of your 13 x 9 x 2-inch baking pan thoroughly. This step is crucial to ensure your brownies don’t stick and release cleanly.

2. Craft the Batter: In a large mixing bowl, whisk together the vegetable oil, water, and the room-temperature eggs. Ensure these wet ingredients are well combined.

3. Incorporate the Brownie Mix: Add the contents of the premium brownie mix to the wet ingredients. Stir until all the ingredients are just moist and a batter forms. Be careful not to overmix at this stage; a few small streaks of flour are acceptable.

4. Spread the Base: Spread the prepared batter evenly into the greased baking pan. Use your spatula to ensure a consistent layer across the bottom. This will be the foundation of your fudgy delight.

5. Whip Up the Filling: In a separate bowl, cream together the creamy peanut butter, vegetable oil, granulated sugar, and flour. Once these dry and semi-wet ingredients are well combined, stir in the beaten eggs and vanilla extract. Continue to mix until the filling is smooth and homogenous.

6. Create the Marble Effect: Carefully spread the peanut butter filling over the batter in the pan. Now comes the fun part! Using the tip of a rubber spatula or a knife, gently swirl the filling into the batter, creating a marble effect. You can do this by dragging the spatula through the layers in figure-eights or random patterns. The goal is to create streaks of peanut butter throughout the brownie base, not to completely mix them together.

7. Bake to Perfection: Place the pan in the preheated oven and bake for 40 minutes. It is paramount that you DO NOT OVERBAKE! Overbaking will result in dry, crumbly brownies, and we are aiming for gooeyness. You can check for doneness by inserting a toothpick into the center; it should come out with moist crumbs attached, not completely clean.

8. Prepare the Frosting: While the brownies are baking or cooling, prepare the frosting. In a medium bowl, cream together the prepared rich chocolate frosting and the creamy peanut butter. Stir until they are thoroughly combined and have a smooth, spreadable consistency.

9. Frost and Finish: Once the brownies have baked for their allotted time, remove them from the oven. You can either spread the peanut butter frosting over the brownies immediately after baking while they are still warm, which will create a slightly melted, glossy finish, or allow them to cool completely before frosting for a firmer layer. Either method is delicious!

Expert Tips & Tricks

• Room Temperature Eggs: Using room temperature eggs in the batter ensures they emulsify better, leading to a more tender brownie crumb. If you forget to take them out in advance, place them in a bowl of warm water for about 10 minutes.
• Don’t Overmix the Batter: Overmixing the brownie batter can develop the gluten in the flour too much, resulting in tougher brownies. Mix just until combined.
• The Marble Technique: For the best marble effect, don’t over-swirl. A few deliberate swirls will give you distinct pockets of peanut butter without losing the integrity of the brownie layers.
• Cooling is Key: While the urge to dive in immediately is strong, allowing the brownies to cool for at least an hour before cutting will make them much cleaner to slice and allow the flavors to meld.
• Peanut Butter Choice: While creamy peanut butter is specified, feel free to experiment with natural peanut butter. If using natural, ensure it’s well-stirred, as the oil separation can affect the consistency.

Serving & Storage Suggestions

These Ooey Gooey Peanut Butter and Fudge Brownies are best served at room temperature, allowing the textures and flavors to shine. They are wonderful on their own, perhaps with a dusting of powdered sugar or a dollop of whipped cream. For a truly decadent experience, pair them with a tall glass of cold milk, a strong cup of coffee, or even a scoop of vanilla bean ice cream.

Leftovers can be stored in an airtight container. At room temperature, they will stay fresh for 2-3 days, maintaining their gooey texture. If you wish to store them for longer, they can be refrigerated for up to 5 days. The frosting might firm up slightly in the refrigerator, so you can let them sit at room temperature for a few minutes before serving to soften. These brownies also freeze exceptionally well. Wrap individual portions tightly in plastic wrap, then place them in a freezer-safe bag or container. They will keep for up to 2-3 months. Thaw frozen brownies at room temperature.

FAQs (Frequently Asked Questions)

Q: Why are my brownies dry after baking?
A: This is most likely due to overbaking. Ensure you are baking for the precise 40 minutes and check for doneness with a toothpick – it should come out with moist crumbs, not clean.

Q: Can I use chunky peanut butter instead of creamy?
A: Absolutely! Chunky peanut butter will add a delightful textural contrast to the gooey filling. Just make sure it’s well-stirred.

Q: How do I prevent the peanut butter filling from sinking to the bottom?
A: Spreading the filling evenly over the batter and then swirling it gently helps to integrate it. Avoiding over-swirling will also prevent it from becoming too thin and sinking.

Q: Can I make this recipe ahead of time?
A: Yes, the brownies can be baked a day in advance and stored at room temperature. The frosting can also be made and stored separately in an airtight container.

Q: What’s the best way to cut clean brownies?
A: For the cleanest cuts, let the brownies cool completely. Use a sharp, long knife and wipe it clean between each cut.
